I can't handle smoothies or food right after a long ride but since I ride out from my home mostly, I do have the advantage of keeping stuff in the fridge. My # 1 favorite is chocolate almond milk as I walk around, cool down, check and prep my bike. It has chocolate and some nutrition from the almond milk plus it is not thick, and not too many calories. My # 2 go to is an iced latte made with espresso, coffee, honey and coconut water with a shot of soy or almond milk. I make this up in batches and just keep a quart jar opf it in the fridge. When I have cooled down, showered and changed then I can eatwithout being ravenous or thirsty.
